New on this forum but been RVing for about 11 years. I liked the looks of this site and thought I'd see what you folks thought about my issue. I'm driving a 2007 Revolution with the C9 engine.

On my last trip out after an overnight stop in route, I had a normal start in about 35 degree weather. Oil pressure came up good. After 5-10 minutes checking outside before pulling out, the engine died like the key was shut off. Check engine light was on. All looked good so I tried a restart. It was normal and the check engine light went off. The same thing happened again and after restarting again, I decided to attempt the 2 hrs. to my destination for the week. We finished that leg of the trip with no issues.

One week later on my return trip, I started up in 17 degree weather after a good 6 hrs. of engine heat and I waited for the engine to die again. It didn't! About 3 hrs. in to my return home, in slow traffic the engine died when I let off the throttle in traffic but restarted from a rolling start when throttle was added back. This happened one more time within minutes with the same restart. Each time the check engine light came on but promptly went out with restart.

I am scheduled to have it put on a Cat. computer later this week but wondering if there are any suggestions. Unit has 93,000 miles and was last serviced about 7,000 miles ago.

Jlobell, Cat C-9 shut down off and on. It sounds like you have a atmosphere pressure sensorfailure. Part Number # 161-1703 and May generate a event code of 108-3, or 108-4.Dave Atherton Retired Cat Mechanic

Jerry, you should get codes from your display in the center of the dash but they will only be displayed when the code is active or check engine light on and in N. Once the light goes out the light bar will not display any logged codes even though they are stored.
